Answer:
44ft
Step-by-step explanation:
The formula for circumference is 2 * π * radius and in this case we want to use 3.14 for π and so we do 2 x 3.14 x 7 because the radius is half of the diameter (14) and once you do that you end up getting 43.96 and once you round you get 44ft so you are correct.
Answer:
no
Step-by-step explanation:
Answer:
The degree is zero
Step-by-step explanation:
we know that
The degree of a constant monomial is always zero
so
In this problem we have
-2
The number -2 represent a constant monomial
therefore
The degree is zero
Answer: multiply and estimate
Step-by-step explanation:
Answer:
given the circumference is 30t.
Step-by-step explanation:
The circumference of a circle is 
and the area of a circle is 
assuming the radius is 
for the circle in question.
We are given the circumference of our circle is 
.
If we solve this for r we get: 
. To get this I just divided both sides by 
since this was the thing being multiplied to .
So now the area is 
.
Simplifying this:
.
30/2=15 so:
.
Squaring the numerator and the denominator:
Using law of exponents or seeing that a factor of 
cancels:
